Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a skirt detachably attached to an air cushion boat.

<Prior Art and its Problems> Conventionally, this kind of material has been formed from a rubber-coated cloth on one side or a single resin-based material.

However, this type of skirt had a grounding portion that was severely worn and had poor durability, and had a single color and had no decorative effect.

<Means for Solving the Problems> The present invention has been made in view of such circumstances, and the means is to construct the skirt body by separate rubberized cloths for the ground side and the hull side, and the ground side has both sides. It is a rubberized cloth, and the hull side is formed by a single-sided rubberized cloth.

<Operation> The grounding side and the hull side can have different colors, and the wearability on the grounding side is improved.

<Embodiment> An embodiment of the present invention will be described with reference to the drawings based on a bag type, but is not limited thereto.
Of course, the same applies to the finger type.

The air cushion boat main body A has a form and structure well known in the technical field of this kind, and a propeller is rotated by an engine installed at the rear portion of the boat body a to generate wind, and a part of the air cushion boat body A is placed under the boat body a. From inside the skirt body b,
The air is blown from the blowout holes (not shown) provided on the inner peripheral surface of the skirt body b to the ground or the water surface to float, and the remaining wind is sent backward to travel as a propulsive force.

The skirt body b has a grounding side 1 and a hull side 2 made of different rubberized cloths, and synthetic rubber such as chloroprene rubber (CR) or chlorosulfonated polyethylene (CSM) is attached to one or both sides of a nylon base cloth. Alternatively, the hull a is made of a so-called rubberized cloth coated and has a known shape according to the size and shape of the hull, with the base cloth side or the rubber side as the surface.
It is detachably attached to the outer peripheral edge of the lower surface of the fastener with a fastener 3, and has a well-known form in which a large number of blowing holes (not shown) are formed on the inner peripheral surface thereof and a drainage port (not shown) is opened on the bottom surface. If necessary, a surface treatment agent may be applied to the ground side surface.

The ground-side rubberized cloth 1 has both front and back sides of the base cloth having rubber surfaces, and chlorosulfonated polyethylene is used from the viewpoint of maintaining durability, a rubber sheet is attached to the front side and a paste-like side is attached to the back side. It is a coated material, and a reinforcement cloth is attached around the blowout hole. In order to reduce the weight of the hull side 2, only one side of the base cloth has a chloroprene rubber surface. The grounding side 1 and the hull side 2 are joined together with an adhesive, sewing or both.

<Effect> In the present invention, the skirt body is composed of different rubber lining cloths for the grounding side and the hull side, and the grounding side is formed by the double-sided rubber lining cloth and the hull side is formed by the single-sided rubber lining cloth. The abrasion resistance of the side is improved and the side becomes durable, and by providing different colors for the grounding side and the hull side, it is possible to provide a decorative effect.

[Brief description of drawings]

The drawings show an example of a skirt of the air cushion boat of the present invention. Fig. 1 is a perspective view of the skirt mounted on the hull, Fig. 2 is a partially cutaway sectional view, and Fig. 3 is an enlarged view of essential parts. It is a sectional view, in which b is the skirt body, 1 is the ground side rubberized cloth,
2 is a rubber-coated cloth on the hull side.
